DVD is probably best for this because you can hop around easier between scenes. The Slip-Up occurs in the 6th scene where Susan Sarandon's Character and Mr. Delacroix are talking about his son Walter. The exact time of the slip-up is 40:00 (at least according to my DVD). What happens is in the background, while they're having this super serious talk, you see what I assume to be a crew member walking past the window. He comes from the left side, walks about a quarter of the way by the window, then turns and sprints back the way he came. Its any interesting juxtaposition... a really emotional scene with this guy strolling around carelessly in the background. The slip-up is only a couple seconds long.
